construct and arrange the stile as that its interference with people getting on and off the car will be reduced to a minimum.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is detail elevation showing part of a street car with my invention applied. Fig. II is a plan or top view. Fig. III is a horizontal section taken just beneath the platform of the car on line III III, Fig. IV. Fig. IV is a vertical section taken on line IV IV, Fig. III. Fig. V is an enlarged detail section showing the head of the turnstile. Fig. V1 is a section taken on line VI VI, Fig. V. Fig. VII is a detail side view of the head. Fig. VIII is a bottom View of the under side of the ratchet-wheel that controls the movement of the stile and operates the register. Fig. IX is a side View of the same. Fig. X is an enlarged detail vertical section taken on line X X, Fig. VII.

1 represents the platform of a car, which is divided transversely of the length of the car by a partition-bar 2, thus forming an ingoing passageway 3 and an outgoing passage-way at, between which the shaft 5 of the stile is located, the shaft being inclosed within a sleeve or tube 6, that passes through the platform of the car and serves as a shield and assists in supporting the shaft. The lower end of the shaft is stepped into a strap 7, secured to the under side of the platform of a car. The upper end of the shaft is jonrnaled in the bar 2. (See Fig. V.) The lower end of the shaft carries a wheel or disk 8, that is keyed or otherwise fixed to the shaft, so as to turn therewith, and the periphery of Which is formed with ratchet-teeth to receive a dog the arms 22.

or pawl 9, (see Fig. 111,) that holds the shaft from turning backward.

At the ingoing side of the platform there is a step or section 10, supported by springs 11, that rest.- on straps 12, secured to the under side of the platform of the car. To one of these straps there is pivoted a lever 13, the inner end of which engages shoulders 14, formed in the upper face of the disk 8, and the outer end of which is connected by a stem 15 to the step 10, so that when a passenger treads on the step he will cause the lever 13 to release the disk and permit the turning of the shaft forward, and as the shaft turns forward one of a series of projections 16 on the under side of the disk comes against one end of a bellcrank lever 17 (see Fig. IX) and operates a register, to which the other end of the bell-crank lever is connected by a cord 19, a spring 20 being employed to return the parts to their normal position as soon as the projection leaves the lever.

Fixed to the upper end of the shaft is a head 21, having arms 22. These normallylocked arms are so connected to the head that when unlocked they will yield and permit a passenger to leave the car without turning the shaft 5, while they do not yield, independently of the head and its shaft, to a passenger getting onto the car. The manner shown of connecting the arms to the head consists of plates 23-one for each arm-that are hinged at 24 to the head 21. Each plate has a short tubular projection 25, that receives one of The-arms are made hollow, and within each is a coiled expansion-spring 26 and a piston 27, the piston being made fast to the head 21 by a stem 28 and a pin 29. The hinged ends of the plates 23 are away from a person entering the car, so that in pressing against an arm he does not tend to swing the plate on its hinge, and to prevent a person from pulling thearm toward him, and thus entering the car without rotating the shaft and operating the register, I provide a lock for the free end of the plate 23, that, as shown, consists of a sliding rod or bar 30, having L-shaped projections 31, (see Fig. X) that enter perforated cars 32 on the plate. There is of course a rod 30 for each plate. The rods fit in perforations or holes 33, formed in the head 21, and the head is slotted at 34 for the play of the projections 31. The rods are held in their lower positions by springs 35, located between the head 21 and heads 36 on the rods.

For the purpose of automatically unlocking the plates 23, and thus permitting the plates to swing on their hinges when the arms are pressed against by persons leaving the car, I employ a step 37 in the passage-way 4, that is supported by springs (see Fig. IV) 38, that rest on straps 39, secured to the under side of the platform of the car. To one of these straps is pivoted a lever 40, one end of which is connected to the step 37 by a stem 41 and to the other end of which there is connected a rod or bar 42, that passes up through the platform of the car and terminates, as shown in Fig. VII, just beneath the position occupied by the rods 30 when the stile is in its normal or lixed position. As a passenger leaves the car he treads upon the step 37, which lifts the rod or bar 42 through means of the described connection between the step and bar, which by lifting the rod 30 unlocks the plate 23, so that the arm 22 will swing freely away from him on the hinge 24 without turning the head 21 of the shaft 5. As the passenger releases the arm it is drawn back to its normal position by the spring 26 and the latch again engages the plate and holds the arm in its extended position, and to prevent the arms being returned with too much force and speed I employ the pistons 27 and make small perforations 43 in the closed ends of the arms, so that the arms can only return to their normal positions so fast as air will enter their outer ends through the perforations 43.

It is manifest that various changes may be made in the details of construction of the different parts, and I Wish it understood that my invention is not confined to such details of arrangement and construction.

I claim as my invent-i0n l.

2. In a turnstile, the combination of a shaft, arms carried by the shaft, hinged plates to which the arms are connected, and means for automatically releasing the plates when the arms are to be moved in one direction, substantially as described.

In a turnstile, the combination ofa shaft, arms carried by the shaft, hinged plates to which the arms are connected, latches for holding the plates in their normal positions, springs for returning the arms to their normal positions, and means for automatically moving said latches, substantially as described.
